my safe5 Once the USB is plugged in ，under Show “Install XXXX 2.8.3” I forgot the details，
I remember my safe5 installed 2.8.3 firmware , I didn’t click anything, unplugged it and plugged it back in, and it was normal.·· 
Was it caused accidentally? z
Everything works normally, but once show install 2.8.3 ```` is BUG ??
haha my ENG not good
